The report says the average driver in the nation will be involved in a crash once every 10 years. But it happens once every 9.3 years in Salt Lake City, and once every 8.3 years in West Valley City, the study said, based on data for drivers there who are insured by Allstate.

The study said that for the larger Salt Lake metro area, including all nearby suburbs, drivers are in crashes once every 9.8 years — about the same as the national average.

The new report also includes data for how often drivers have “hard braking” events — which it said indicates unsafe driving behavior such as following too closely, or aggressive or distracted driving. It is measured by people who voluntarily use Allstate’s Drivewise telematics program that rewards safe drivers with cash.

The average driver nationally has 19 hard-braking events per 1,000 miles traveled. In Salt Lake City, it is 22.2, and in West Valley City, it is 22.1. For the overall Salt Lake metro area, it’s 17.8.

“We hope this year’s Best Drivers Report encourages more people to buckle up, slow down and minimize distractions to reduce their risks when they’re traveling over the holiday and all year-round,” said David Harkey, president of the Insurance Institute for Highway Safety.

The nation’s safest large city for driving, the report said, is Brownsville, Texas, where drivers go an average of 13.6 years between crashes — 26 percent better than the national average.

The worst large cities to drive in America were Baltimore, where an average driver is in a crash every 3.8 years; Boston and Washington, every 3.9 years; Worcester, Mass., every 4.4 years; and Glendale, Calif., every 5.1 years.

Utah drivers have been ranked lower (so better) in some other national surveys in recent years.

In December, Utah drivers were ranked third worst in the nation in a study by QuoteWizard, a website for comparing car insurance. That actually was an improvement because the previous year, it ranked Utah as having the nation’s worst drivers.

That study looks at such things as car crashes, traffic tickets and drunken driving.

Four years ago, Insure.com ranked Utah drivers as the 10th rudest in the nation.

But on the other end of the spectrum, CarInsuranceComparison.com ranked Utahns as the nation’s second-best drivers in 2014, based largely on low fatality and drunken-driving rates.
